JE ELRY.

To all whom it may concern Be it known that I, RUnoLr BRETTNER, a citizen of the United States, residing at New York, in the borough of New York and State of New York, have invented a new and useful Improvement in Jewelry, of which the following is a specification.

This invention relates to improvements in jewelry and the object is to provide a bracelet, ring, necklace, or other article of jewelry composed of units of rectangular, round or other contour forming a base to which the ornamentation is secured, said units being so constructed that they may be flexibly connected without the use of solder, the structure being such that any jeweler may make up an article of jewelry from the units without the necessity of utilizing the services of a manufacturer.

With the above object in view,'the invent'on consists in the novel features of const uction hereinafter fully described, particularly set forth in the claims, and clearly illustrated by the accompanying drawing, in which, i

Figure 1, is a longitudinal sectional view of two units embodying one form of my invention; Fig. 2, a similar view on the-line 22 of Fig. 1; Fig. 3, a longitudinal sectional view of two units showing another form of the invention; Fig. 4, a similar view on line 4 l of Fig. 3; Fig. 5, a longitudinal sectional View of two units showing still another form of the invention; Fig. 6,-a similar view of the same on line 66 of Fig. 5; Fig.7, a transverse sectional view; Fig. 8, a. similar view taken on the line 8-8 of Fig. 6; Fig. 9, a longitudinal sectional view of another form of the invention; Fig. 10, a similar view taken at right angles to the section shown in Fig. 9, and showing the prbjections 14 heat to prevent disengage? ment of the conneeting'members; Fig. 11, a transverse section on line 11-11 of Fig. 10; Fig. 12, a similar View on line 12-12 of Fig. 10, and Fig. 13, a'perspcetive view of one of the connecting-members.

in the. drawing, I have shown the units as rectangular in form, but it will be understood that they may be of other forms, as for instance, round or ring-like.

Referring now more particularly to the drawing. Figs. 1 and 2, the numeral 1 designates the units of which as many are used as may be necessary to form the desired article of jewelry. Each unit has on one Specification of Letters Patent.

side ofits center, the pair of pron s 2 which are struck out from the metal oi the unit,

and on the opposite side of its center, an opening 3. To. assemble the units the prongs 2 of' one are inserted through the opening 3 of the other and their pro ecting ends bent back to hold the two units from disengagement, but in flexible connection.

Referring now to Figs. 3 and 4 of the drawing, the numeral 4 designates theunits, each of which has formed therein, on each side of its center, an opening 5. In this form of the invention, the units are connected by inserting through the coincident openings 5 of the adjacent units, a conmeeting-member 6 having a T-head and prongs 7, the projecting ends of which are bent back as shownr In Figs. 5, 6, 7 and 8, the numeral 8 designates the units, each of which has formed on each side of its center a T-shaped opening 9. The metal of the longer portion of the T-shaped opening is not cut entirely away from the metal of the unit but is bent outward as at 9 as shown. The units are held together by a connecting-member 10, having a T-head at each end. After inserting this number 10 in the T-shaped openings the metal 9 is bent inward to close the larger-portion of said openings, thus preventing the disengagement of the connect-- ing-member 10 from the units.

In the structure shown in Figs. 9, 10, 11, 12 and 13, I have designated the units by the numeral 11. Each unit has formed on each side of its center, a T-shaped opening 12, as in the form shown in Figs. 5 and 6, except. however, that all of the metal is cut out. Two connecting-members 13 are provided to connect each two units, these connecting members having T-heads at each end, and one having projecting beyond each end, a prong 14. \Vhen these two connecting members are inserted in the T-shaped openings of the adjacent units, the prongs l-l of one are bent down at the ends of the T-heads of the other, so that one member cannot be moved independently of the other to disengage the T-openings, and inasmuch as their combined thickness is greater than the width of the larger portion of theT- opening. it will be seen that disengagement is impossible.

From the above description it will be seen that I have provided a number of units which can be readily connected or disconneeted without the use of solder, and that anv article of jewelry may be formed therefrom by a jeweler without the use of tools other than pliers. It willv be understood that the units may be made of any kind of metal and may be ornamented with any kind of ornamentation of metal and precious stones.

It will be noted that in all of the forms shown the units are held 'in substantially close relation with each other and the connecting element is not visible and does not constitute a Visiblelink of the complete article. g

Having thus fully described my invention What I claim as new and desire to secure by Letters Patent of the'United States, is:

1. An article of jewelry composed of units each consisting of a single integral element and having openings formed upon opposite sides of its center, said units being placed with adjacent sides in contact with each other, and aeonnecting member adapted to be inserted through the opening of one unit and to engage the inner wall thereof and to hold said un ts in close relatlon, said connecting memberbeing substantially concealed by said units.

tions of the members being adapted to engage in the smaller portions of the openings,

and a bendable lip formed on one edge of the larger portion of each opening, said units being arranged in substantially close relation to each other, said lips being adapted to close the larger portions of the openings to prevent disengagement of the members therefrom.

3. An article of jewelry composed of units having each substantially T-shaped openings formed on opposite sides of its center, connectingmembers formed at each end with a T-head adapted to be inserted in the T-shaped openings of the units, and means, for partially closing said openings.

at. An article of jewelry composed of units having each substantially T-shaped openings formed on opposite sides of its center,

the metal of a portion of each opening being pressed out but not cut off, and connectingmembers formed at each end with a T-head adapted to be inserted in the T-shaped openings, said portions of the metal pressed out from said openings pressed in to partially close said openings and preventdisengagement of the connecting-members.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
